Attendance Introduction to DSLR Attendance will be taken at the beginning of each class and after the break Late students will be admitted to class but the late will be documented for future reference It is the responsibility of the student to get information they have missed
Behaviour & Preparedness Introduction to DSLR The classroom is a professional office/studio No cell phones, texting, email or social media No food in class Drinks in class with spill proof container Respect the rights and opinions of others During critiques comments should be constructive

hotography - Exposure Exposure is dependent on 3 variables 1. ISO – Film/Sensor sensitivity tolight (adjusting sensitivity will brighten or darken the image) 2. Shutter Speed (time that light is allowed to expose image sensor) 3. Aperture (size of the opening that allows light to expose the image sensor) Exposure Triangle
Lower ISO, sharper images, allow you to enlarge or crop images better Photography – ISO Sensitivity
Most common ISO settings 100 200 400 800 1600 3200 Less sensitive to light More sensitive to light Low noise, higher quality More noise, lower quality Photography – ISO Sensitivity

Shutter Speed Controls the amount of time that the sensor\film is allowed to be exposed to light. Photography – Shutter Speed
The faster the shutter speed (ex. 1/125 1/250 1/500 1/1000 1/2000 1/4000 1/8000) the faster the motion that can be stopped. Photography – Shutter Speed
Example of fast shutter speeds. Fast shutter speed like 1/1000th sec. freezes action
Slower shutter speeds (ex. 1/4 1/8 1/15 1/30 1/60) allow more light in darker areas and/or show motion. Shutter speeds longer than 1/60th require a tripod to prevent camera shake Photography – Shutter Speed
Long shutter speed like 1 second will cause blur in moving water
Panning Using a slow shutter speed when photographing a fast moving subject Photography – Shutter Speed
Moving the camera in the same direction & speed as the subject will keep the moving subject sharp while blurring the background creating the feeling of motion & speed. This technique is called “Panning”
Controls the amount of light that the sensor receives. Photography – Aperture f/22 Small Aperture f/2.8 Large Aperture
Photography - Aperture A common progression of apertures is: 2, 2.8, 4, 5.6, 8, 11, 16, 22 More light (brighter) Less light (darker) Each is double or half the amount of light of the next aperture number. Ex. Two stops brighter (5.6 to 2.8 = 4x the original amount of light) Photography – Aperture
The light meter in our cameras sees every scene as the same middle gray tone (18% reflectance). Light or dark scenes are shifted to this mid tone with auto exposure & must be corrected manually by the photographer. Bright scenes should be given more exposure (+1 or +2 or +3) & darker scenes should be given less exposure (-1 or -2 or -3) Photography – Exposure
If we have an “average” scene we can use the default exposure. If we have a bright snow or beach scene, we need to add more light (+). If we have a dark or night scene, we need less light (-). When in manual mode, by moving either shutter speed or aperture dials we can correct for brighter or darker than normal scene brightness. If working in any of the automatic modes, the exposure compensation dial is used to add (+) or subtract (-) light from the exposure. Photography – Exposure
Photography – Exposure Making several photos at varying settings like this is called “bracketing”& will allow you to select the best exposure later. In this series the +2 looks best.

All light Sources have a different colour temperature. In order to ensure accurate colour in your images you should match your white balance setting on your camera to that of light source. Photography – White Balance
White Balance is based on white light, which is approximately the same colour temperature as sunlight (mid day). Photography – White Balance
Here are common white balance settings on your camera Photography – White Balance
